Explanation:

preposition: and

Answer 2

Answer:

Option A is correct.

Explanation:

A preposition is a word which shows the relation of a noun or pronoun to another word in a sentence. On the other hand, a gerund is a verb which acts like a noun and a noun refers to the word which can be a name of any person, animal or thing.

Here, option A is correct. In order to combine sentences preposition should be followed by noun or gerund. In this sentence, 'of' is a preposition followed by 'working' a gerund, thereby retaining the true meaning of the sentence.

Option B has conjunction in it. So, it is incorrect.

Option C is not appropriate in its meaning. So, it is incorrect.

Option D is irrelevant.  So, it is incorrect.
